2. Description of the Related Art

Wireless communication devices, such as cell phones, typically include antennas for transmitting and receiving radio frequency (RF) signals. In order to achieve higher bandwidth, lower latency, and higher data transmission rates in wireless communication devices, millimeter wave frequency bands are introduced. However, the millimeter wave transmission brings many technical challenges. One of the major problems is the high path loss when the signal propagates. Therefore, directional antennas are commonly used in wireless communication devices (such as smart phones) to increase the gain of the signal. However, to configure multiple directional antennas radiating in various directions, a wireless communication device may be equipped with multiple antenna modules, which would increase the cost and the size of the wireless communication device.

DETAILED DESCRIPTION

FIG. 1A illustrates a perspective view of a part of a semiconductor device package 1, in accordance with some embodiments of the present disclosure. FIG. 1B illustrates a cross-sectional view of the part of the semiconductor device package 1, in accordance with some embodiments of the present disclosure. The semiconductor device package 1 includes an electronic component 10, a circuit layer 11, a dielectric layer 12, antenna layers 13, 14 and a circuit layer 15.

The electronic component 10 has a surface 101 (e.g., a backside surface), a surface 102 (e.g., an active surface) opposite to the surface 101 and a lateral surface 103 extending between the surface 101 and the surface 102. The electronic component 10 may be a chip or a die including a semiconductor substrate, one or more integrated circuit devices and one or more overlying interconnection structures therein. The integrated circuit devices may include active devices such as transistors and/or passive devices such resistors, capacitors, inductors, or a combination thereof. In some embodiments, the electronic component 11 may be or include a semiconductor package device or a system in package (SiP).

The circuit layer 11 (or building-up circuit) surrounds the electronic component 10. For example, the circuit layer 11 is disposed on the surfaces 101, 102 and the lateral surface 103 of the electronic component 10. The circuit layer 11 may be connected to (or attached to) the surfaces 101, 102 and the lateral surface 103 of the electronic component 10 through an adhesive layer 10 h (e.g., a tape or an attach film). For example, the adhesive layer 10 h is in contact with the surfaces 101, 102 and the lateral surface 103 of the electronic component 10. For example, the adhesive layer 10 h is in contact with the circuit layer 11. The circuit layer 11 may be or include a flexible material, so that the circuit layer 11 can be bent to surround the electronic component 10. In some embodiments, the circuit layer 11 may be or include a flexible printed circuit board (FPC).

The circuit layer 11 may include one or more conductive layers (e.g., redistribution layers, RDLs, conductive vias, conductive pads or the like) 11 c, 11 v and one or more dielectric layers 11 d. A portion of the conductive layer 11 c is covered or encapsulated by the dielectric layer 11 d while another portion of the conductive layer 11 c is exposed from the dielectric layer 11 d to provide electrical connections. For example, the electronic component 10 may include conductive pads (or pins or bumps or pillars) 10 p on its surface 102, and the conductive pads 10 p are electrically connected to the conductive layer 11 c of the circuit layer 11 through, for example, electrical contacts (e.g., solder balls or bumps) 10 s. The circuit layer 11 may be electrically connected to the circuit layer 15 through conductive vias 12 v penetrating the dielectric layer 12.

In some embodiments, the dielectric layer 11 d may include pre-impregnated composite fibers (e.g., pre-preg), Borophosphosilicate Glass (BPSG), silicon oxide, silicon nitride, silicon oxynitride, Undoped Silicate Glass (USG), any combination of two or more thereof, or the like. Examples of a pre-preg may include, but are not limited to, a multi-layer structure formed by stacking or laminating a number of pre-impregnated materials/sheets. In some embodiments, there may be any number of conductive layers or dielectric layers depending on design specifications. In some embodiments, the conductive layers 11 c, 11 v may be formed of or include gold (Au), silver (Ag), copper (Cu), platinum (Pt), palladium (Pd), other metal(s) or alloy(s), or a combination of two or more thereof.

The dielectric layer 12 is disposed on the circuit layer 11. The dielectric layer 12 may be conformally disposed on the circuit layer 11. In some embodiments, the dielectric layer 12 may be or include a dry film. In some embodiments, a dielectric constant (Dk) or a dielectric loss tangent (Dk) of the dielectric layer 12 is less than a Dk or a Df of the surface 101 and the surface 102 of the electronic component 10. In some embodiments, the Dk and the Df of the dielectric layer 12 is less than a Dk or a Df of silicon.

The antenna layer 13 (or antenna module) is disposed over the surface 101 of the electronic component 10. The antenna layer 13 is in contact with the dielectric layer 12. The antenna layer 13 may include an antenna pattern 13 a and a dielectric layer 13 d. The antenna pattern 13 a is partially embedded within the dielectric layer 13 d, and a top surface of the antenna pattern 13 a is exposed from the dielectric layer 13 d. For example, the top surface of the antenna pattern 13 a is substantially coplanar with a top surface of the dielectric layer 13 d. In some embodiments, the antenna pattern 13 a may function as a director and the conductive layer 11 c of the circuit layer 11 may function as a radiator. The antenna pattern 13 a may be configured to radiate electromagnetic wave in a direction substantially perpendicular to the surface 101 of the electronic component 10.

In some embodiments, the dielectric layer 13 d may include pre-impregnated composite fibers (e.g., pre-preg), BPSG, silicon oxide, silicon nitride, silicon oxynitride, USG, any combination of two or more thereof, or the like. Examples of a pre-preg may include, but are not limited to, a multi-layer structure formed by stacking or laminating a number of pre-impregnated materials/sheets. In some embodiments, there may be any number of antenna layers or dielectric layers depending on design specifications. In some embodiments, the antenna layer 13 a may be formed of or include Au, Ag, Cu, Pt, Pd, other metal(s) or alloy(s), or a combination of two or more thereof.

The antenna pattern 13 a may have various shapes depending on different design requirements. For example, as shown in FIGS. 1C, 1D, 1E, 1F, 1G, and 1H, which illustrate top views of the antenna layer 13, the antenna pattern 13 a may be rectangular (e.g., FIGS. 1C and 1F), circular (e.g., FIGS. 1D and 1G), or irregular (e.g., FIGS. 1E and 1H). In some embodiments, the antenna pattern 13 a may include an open-loop pattern as shown in FIGS. 1C, 1D, and 1E. In some embodiments, the antenna pattern 13 a may include a closed-loop pattern as shown in FIGS. 1F, 1G, and 1H.

The antenna layer 14 (or antenna module) is disposed over the lateral surface 103 of the electronic component 10. The antenna layer 14 is in contact with the dielectric layer 12. The antenna layer 14 may include an antenna pattern 14 a and a dielectric layer 14 d. The antenna layer 14 is the same as or similar to the antenna layer 13, and thus the descriptions of the antenna layer 13 can be applicable to the antenna layer 14.

The electronic component 10, the circuit layer 11 and the dielectric layer 12 are disposed on the circuit layer 15 and electrically connected to the circuit layer 15. The circuit layer 15 may include one or more conductive layers (e.g., redistribution layers, RDLs, conductive vias, conductive pads or the like) 15 c, 15 v and one or more dielectric layers 15 d. A portion of the conductive layer 15 c is covered or encapsulated by the dielectric layer 15 d while another portion of the conductive layer 15 c is exposed from the dielectric layer 15 d to provide electrical connections.

The electrical contacts 16 (e.g., solder balls) are electrically connected to the substrate 15 to provide electrical connections between the semiconductor device package 1 with external components (e.g. external circuits or circuit boards). In some embodiments, the electrical contacts 16 includes controlled collapse chip connection (C4) bumps, ball grid array (BGA) or land grid array (LGA).

In some embodiments, the circuit layer 11, the dielectric layer 12, the antenna layers 13, 14, and the circuit layer 15 may be collectively referred to as a substrate (antenna substrate or an antenna module). The substrate may have a first portion on which the antenna layer 13 is disposed, a second portion on which the antenna layer 14 is disposed, and a third portion on which the circuit layer 15 is disposed. The first portion of the substrate extends along the surface 101 of the electronic component 10. The second portion of the substrate extends along the lateral surface 103 of the electronic component 10. The third portion of the substrate extends along the surface 102 of the electronic component 10. For example, the substrate may be conformally disposed on the surfaces 101, 102, and 103 of the electronic component 10.

In some embodiments, the signal transmission between the antenna layer 13 and the electronic component 10 may be achieved by the substrate. For example, the electromagnetic waves or signal received by the antenna layer 13 can be transmitted to the circuit layer 11 through, for example, coupling. The signal is then transmitted along the surface 101, the lateral surface 103, and the surface 102 of the electronic component 10 to the conductive pads 10 p of the electronic component 10 for the subsequent processing. Similarly, the signal from the electronic component 10 may be transmitted along the surface 102, the lateral surface 103, and the surface 101 of the electronic component 10. The signal is then transmitted to the antenna layer 13 through, for example, coupling and radiated by the antenna layer 13.

In some embodiments, the signal transmission between the antenna layer 14 and the electronic component 10 may be achieved by the substrate. For example, the electromagnetic waves or signal received by the antenna layer 14 can be transmitted to the circuit layer 11 through, for example, coupling. The signal is then transmitted along the lateral surface 103 and the surface 102 of the electronic component 10 to the conductive pads 10 p of the electronic component 10 for the subsequent processing. Similarly, the signal from the electronic component 10 may be transmitted along the surface 102 and the lateral surface 103 of the electronic component 10. The signal is then transmitted to the antenna layer 14 through, for example, coupling and radiated by the antenna layer 14.

Since the signal transmission between the antenna layer 13 or 14 and the electronic component 10 is mainly achieved by the substrate, the signal loss and the latency can be reduced by choosing the materials of the substrate having a relatively lower Dk and Df.

In some comparative embodiments, to achieve multiple directional antennas radiating in various directions, a wireless communication device may be equipped with multiple antenna modules. However, this would increase the cost and the size of the wireless communication device. To solve the above problems, a single antenna module having antennas disposed on multiple surfaces of the antenna module is provided. The antennas of said antenna module may be formed by substrate lamination processes or build-up processes. However, as the radiation directions increase, the number of layers of the substrate increases as well, which would reduce the yield rate of the antenna module and adversely affect the performance of the antenna module.

In accordance with the embodiments as shown in FIGS. 1A-1H, the substrate including the antenna layers 13 and 14 is attached to the electronic component 10, wherein the antenna layers 13 and 14 are disposed over different surfaces (e.g., the surface 101 and the lateral surface 103) of the electronic component 10. The substrate includes a FPC board (e.g., the circuit layer 11), so that the substrate can be bendably disposed along the edges of the electronic component 10. The substrate may also have openings to expose corresponding bending portions (or flexions). Hence, the semiconductor device package 1 can achieve multi-directional radiation without increasing its manufacturing cost and size. In addition, a substate having a relatively large number of layers to accommodate the antennas is not required, which can enhance the performance of the semiconductor device package 1.

FIG. 2A illustrates a cross-sectional view of a part of a semiconductor device package 2A, in accordance with some embodiments of the present disclosure. The semiconductor device package 2A is similar to the semiconductor device package 1 as shown in FIG. 1B, except that as shown in FIG. 2A, the antenna pattern 13 a is disposed on the dielectric layer 13 b. For example, the antenna pattern 13 a is not embedded within the dielectric layer 13 b. Similarly, the antenna pattern 14 a is disposed on the dielectric layer 14 b without be encapsulated or covered by the dielectric layer 14 b.

FIG. 2B illustrates a cross-sectional view of a part of a semiconductor device package 2B, in accordance with some embodiments of the present disclosure.

The antenna layer 33 includes an antenna pattern 33 a and a dielectric layer 33 d. The antenna layer 33 is the same as or similar to the antenna layer 13, and thus the descriptions of the antenna layer 13 can be applicable to the antenna layer 33.

Compared with the semiconductor device package 1, the semiconductor device package 3B has more radiation directions. For example, the semiconductor device package 3A is configured to radiate electromagnetic waves in three directions (e.g., a direction away from the surface 101 of the electronic component 10, a direction away from the lateral surface 103 of the electronic component 10, and a direction away from the lateral surface 104 of the electronic component 10). In some embodiments, the semiconductor device package 3B may include one or more antenna layers disposed over the lateral surfaces of the electronic component 10 between the lateral surface 103 and the lateral surface 104, so as to achieve more radiation directions.

The antenna layers 13, 14, 33, 34 a, 34 b, 34 c, and 34 d are disposed over the corresponding edges of the electronic component 10, so as to achieve more radiation directions. Each of the antenna layers 34 a, 34 b, 34 c, and 34 d is the same as or similar to the antenna layer 13, and thus the descriptions of the antenna layer 13 can be applicable to the antenna layers 34 a, 34 b, 34 c, and 34 d.

A heat may be then applied to the structure as shown in FIG. 6B to cure the underfill 10 u (e.g., a reflow operation). A force is then applied to the lateral surface of the electronic component 10 to achieve the first rotation.

Referring to FIG. 6C, after the first rotation, the surface 102 of the electronic component 10 is substantially perpendicular to the top surface of the carrier 49, and a lateral surface 103 of the electronic component 10 facing the top surface of the carrier 49 is connected to the adhesive layer 10 h. The lateral surface 103 of the electronic component 10 is disposed over an antenna layer 14 including the antenna pattern 14 a and the dielectric layer 14 d. As shown in FIG. 6C, the opening 44 h is located at the corner of the electronic component 10. The force is applied to the circuit layer 15 to achieve the second rotation.

Referring to FIG. 6D, after the second rotation, the surface 102 of the electronic component 10 faces away from the top surface of the carrier 49, the lateral surface 103 of the electronic component 10 is substantially perpendicular to the top surface of the carrier 49, and a surface 101 (e.g., a backside surface surface) of the electronic component 10 is connected to the adhesive layer 10 h. The surface 101 of the electronic component 10 is disposed over the antennal layer 13 including the antenna pattern 13 a and the dielectric layer 13 d. A heat can be then applied to the structure as shown in FIG. 6D to cure the adhesive layer 10 h (e.g., a reflow operation or an ultraviolet (UV) curing operation).

Referring to FIG. 6E, the carrier 49 is removed to expose the antenna layer 13. Electrical contacts 16 are formed on the conductive layer 15 c of the circuit layer 15 as shown in FIG. 6F. In some embodiments, singulation may be performed to the structure as shown in FIG. 6F.

As used herein, the terms “substantially,” “substantial,” “approximately,” and “about” are used to denote and account for small variations. For example, when used in conjunction with a numerical value, the terms can refer to a range of variation of less than or equal to ±10% of that numerical value, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. As another example, a thickness of a film or a layer being “substantially uniform” can refer to a standard deviation of less than or equal to ±10% of an average thickness of the film or the layer, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. The term “substantially coplanar” can refer to two surfaces within micrometers of lying along a same plane, such as within 40 μm, within 30 μm, within 20 μm, within 10 μm, or within 1 μm of lying along the same plane. Two surfaces or components can be deemed to be “substantially perpendicular” if an angle therebetween is, for example, 90°±10°, such as ±5°, ±4°, ±3°, ±2°, ±1°, ±0.5°, ±0.1°, or ±0.05°. When used in conjunction with an event or circumstance, the terms “substantially,” “substantial,” “approximately,” and “about” can refer to instances in which the event or circumstance occurs precisely, as well as instances in which the event or circumstance occurs to a close approximation.

As used herein, the singular terms “a,” “an,” and “the” may include plural referents unless the context clearly dictates otherwise. In the description of some embodiments, a component provided “on” or “over” another component can encompass cases where the former component is directly on (e.g., in physical contact with) the latter component, as well as cases where one or more intervening components are located between the former component and the latter component.

As used herein, the terms “conductive,” “electrically conductive” and “electrical conductivity” refer to an ability to transport an electric current. Electrically conductive materials typically indicate those materials that exhibit little or no opposition to the flow of an electric current. One measure of electrical conductivity is Siemens per meter (S/m). Typically, an electrically conductive material is one having a conductivity greater than approximately 10⁴ S/m, such as at least 10⁵ S/m or at least 10⁶ S/m. The electrical conductivity of a material can sometimes vary with temperature. Unless otherwise specified, the electrical conductivity of a material is measured at room temperature.

Additionally, amounts, ratios, and other numerical values are sometimes presented herein in a range format. It can be understood that such range formats are used for convenience and brevity, and should be understood flexibly to include not only numerical values explicitly specified as limits of a range, but also all individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly specified.

While the present disclosure has been described and illustrated with reference to specific embodiments thereof, these descriptions and illustrations do not limit the present disclosure. It can be clearly understood by those skilled in the art that various changes may be made, and equivalent elements may be substituted within the embodiments without departing from the true spirit and scope of the present disclosure as defined by the appended claims. The illustrations may not necessarily be drawn to scale. There may be distinctions between the artistic renditions in the present disclosure and the actual apparatus, due to variables in manufacturing processes and such. There may be other embodiments of the present disclosure which are not specifically illustrated. The specification and drawings are to be regarded as illustrative rather than restrictive. Modifications may be made to adapt a particular situation, material, composition of matter, method, or process to the objective, spirit and scope of the present disclosure. All such modifications are intended to be within the scope of the claims appended hereto. While the methods disclosed herein have been described with reference to particular operations performed in a particular order, it can be understood that these operations may be combined, sub-divided, or re-ordered to form an equivalent method without departing from the teachings of the present disclosure. Therefore, unless specifically indicated herein, the order and grouping of the operations are not limitations of the present disclosure.
